Keep cryptocurrency secure

If you're thinking about investing in cryptocurrency, or already have, this guide will help you how to avoid crypto investment scams as well as keeping your digital wallet safe from theft.

What it is

Cryptocurrency is digital currency. There's no centralised bank or government involved, instead, is kept in a digital 'wallet' and transactions are recorded using technology. There are thousands of different cryptocurrencies available online, including

Cryptocurrency trading largely operates online and is usually unregulated, as such it can be very difficult to differentiate between legitimate cryptocurrency trading platforms and scam ones.  

Wallets

Your digital wallet is software that stores both your private and public and uses blockchain to enable you to send and receive cryptocurrency and check your balance.  

Your private key is essentially a password. It's a long string of letters and numbers that is created the first time you access your wallet. It is very important to keep this key safe and never share it, as it is used to transfer funds out of your wallet. 

Non-fungible tokens (NFTs)

NFTs are certificates of ownership for unique digital items, for example art or music, using the same blockchain technology as cryptocurrency. you purchase are also kept in your wallet and, as such, have similar risks to cryptocurrency. 

How to protect yourself from cryptocurrency investment scams

The main risks with cryptocurrency are scams and theft, and both can result in large financial loss.

Because cryptocurrency is seen by some as a lucrative investment, many investment scams use cryptocurrency as a lure. An investment scam is where you transfer funds thinking you are investing your money into a fund or scheme, but the investment is fake, and your funds are stolen.

  • Social media is not the place for financial advice

    Fake cryptocurrency offers may come from advertising on social media, sometimes using the image of a famous person to promote it. Occasionally, the scammers will take control of someone else's account or copy the account and pretend to be that person. 

  • Be wary of 'out of the blue' offers

    Scammers will start relationships through social media sites, or even online dating sites, to introduce potential victims to a particular cryptocurrency or trading platform. This includes 'exclusive' offers to buy into the launch of a new currency or 'coin'. Turning your social media settings to private will make it harder for scammers to find you on those sites.

  • Do your due diligence

    If you are considering investing or trading in cryptocurrency, do your due diligence to ensure the legitimacy of the trading platform. Scammers can create very realistic looking websites and portfolios. Always check if the company is registered to provide financial services in the country they operate in, and whether any financial regulators have issued warnings about the company.

  • Scams can happen when you buy and sell

    Just like a dodgy trader on marketplace, scammers will try to rip you off when buying and selling cryptocurrency. Only use well-known trading platforms and be wary of anyone offering too good a deal.

How to protect your cryptocurrency from being stolen

In these cases, the criminals try to trick you into giving them your login details or your wallet's private key. Once they have that, they empty your account. Due to a lack of regulation and the nature of cryptocurrency, it can be almost impossible to get your funds back if they are taken. 

  • Never share your private key

    Your wallet's private key is how you access and transfer funds out of your wallet. Sharing it with anyone will give them access to all of your cryptocurrency and anything else you have saved there (such as NFTs). Two-factor authentication (2FA) adds an extra security check on top of your password, making it harder for someone to access your wallet or exchange account. This can be a code from an app or something only you have, such as your fingerprint. 

    Use two-factor authentication to protect your accounts

  • Never forget your private key

    If you forget your private key, you won’t be able to retrieve it anywhere. If you can’t log in to your wallet, you can’t access any of the funds in it. Using a password manager is an easy way to store your passwords and private keys so you don’t forget or lose your important information. They can also generate incredibly secure, randomised passwords.

  • Be wary of phishing emails

    The criminals are trying to get your log in details and one way of doing this is to send you a  email which appears to be from the cryptocurrency service you use. The email will tell you to click a link and enter your details. The link will go to a fake version of the website and is set up to harvest .

    Protect yourself against phishing scams

  • Look out for fake apps

    Criminals can create fake cryptocurrency trading apps and then advertise them on social media or directly message you about them. The app asks you to log into your wallet, it looks like it fails to work, but it has actually sent your credentials to the criminals.

  • Keep your wallet in a safe place

    Your cryptocurrency wallet needs to be kept securely, either on your own device or with an exchange. If you prefer to use an exchange’s wallet services, look for a reputable one. Using an exchange is like using other online services. If it suffers a cyber attack, access to your wallet could be temporarily unavailable or completely locked out. If it goes out of business, you’ll lose your cryptocurrency.

  • Maintain a back-up

    Wallets which are used to store cryptocurrency must be backed up to offline storage to protect you from losing your wallet if anything goes wrong. For example, if you're targeted by ransomware, your device breaks or your wallet is accidentally deleted. Test your backup so you know you can restore it if you need to. 

    Backing up your data and devices

  • Set up encryption

    Encrypting your devices will reduce the risk that even if an attacker gets physical access to them could extract your wallet while the device is powered off or locked. The steps to setting up depends on the device and operating system.
